On-line monitoring of the supercritical fluid extraction with proton nuclear magnetic resonance spectroscopy

Supercritical fluid extraction is performed with carbon dioxide as eluent. The extraction process is monitored with hydrogen NMR spectroscopy as the detection technique. It is shown that the extraction process can be easily controlled with the information provided by the NMR spectra.
